In a repository with deltas, I've a problem sometimes at 'update' with autosync.

In linux, I've seen sometimes:
<verbatim>
$ fossil update mybranch
Autosync:  http://fossil/cgi-bin/project
                Bytes      Cards  Artifacts     Deltas

fossil: cannot access baseline manifest ]�:+�12273d5ab9
</verbatim>

On cygwin (fossil build in cygwin), I see segmentation faults.

Rerunning the command, where it does not sync anything new, it works.
